Princess Cadence and Shining Armor are a happily married couple, however, certain situations had left them far busier than their usual duties back in Canterlot. Now ruling over the Crystal Empire after Sombra's return and defeat, they barely see each other as they helped modernize the crystal ponies after a thousand years being banished with the evil unicorn king, only late at night when they head for bed, barely sharing a minute to snuggle before passing out. Their mental and physical exhaustions aren't threatening to tear their marriage apart, knowing what they were getting into. Desires can be hard to maintain, especially sexual desires, and Cadence was going to give in and have an intimate evening with her loving husband, even if he's passed out hard from training new guard recruits all day and night.
